' 1 Application filed June 22,

To all whom it may concern r Be it known that 1, MAX Pon'nscn', acitizen of the United States, and a resident of Ridgewood, in the countyof Bergen and State of New Jersey, have invented a new and ImprovedTeasel-Cleaning Machine, of which the following is-a full, clear, andexact description. v

This inventionrelates to machinery used in the manufacturing of napgoods and par ticularly to an improved teasel cleaning machine and hasfor an object to provide a construction which will automatically cleanaseries of teasels in a minimum time.

Another object of the invention is to pro vide a machine wherein anentire: frame of teasels may be cleaned at one operation auto matically;

' A still further object of the invention is to provide a cleaningapparatus in which ing the teasels. V

Heretofore, in the use of teasers, it has been customary to arrange anumber of 'teasels in a frame and to use these teasels for raising thenap on certain goods, When.

the teasels are in use, it is customary to have the goods on which theyare used moist or 'wet and, consequently, the teasels become wet duringcontinued use and also become clogged or filled with the nap pulled from.the cloth. After a certain amount of use,

. ingrooms and left until dried, which would This take fromseveral'h'our's to a day. necessitates not only a large sum of money butpresents an unpleasant dusty work, more or less unhealthy for the menwho perform.

the cleaning operation. Then the work was done manually, the pressureexerted on the teasels was not uniform and, consequently, an appreciablenumber of teasels were in ured whereasin the presentsltructurethepressure and other action are even and may be adjusted to suit variousconditions where by the teasels are not only cleaned but betterpreserved.

In the present invention, a construction has been presented whichquickly cleans the teasels while wet so that they are ready for use in averyshort time, the operation being continuous fromthe timethe teaselcarrying frame is inserted into the machine until it is discharged readyfor-use. I

Referring to the accompanying drawings by, numeral, 11 indicates a frameof any de sired kind, preferably of angle iron supplied with. suitablebraces and other members for carrying the various parts ofthe machine.

The frame 11 has mounted thereon four.

sprocket wheels, namely, sprocket wheels 12,

13 ll and 15, said sprocket wheels carrying.

the frame 11 and preferably passes over a U-shaped supporting guide 19,which guide is cut away at the bottom near the ends to' permit the chainto pass through.

a As indicated inFigure 7, this guide permits the chain to freely movebut prevents any appreciable Wabbling and also acts as a lateral supportfor the respective frames 18 which are placed on the chain between thesides 20and 21 so that the various teasels 2-2 will be held upright asthe stops 17 are pushed against the ends of the frames. It

willbe noted that the frames 18 are of the usual. ronstriiction whichare now in common use and cons t of a pair of side plates held by screwsor other means and forming long sockets for receiving the stems of thevarious teasels 2. The stems are squeezed firmly by the frames so as tohold the same in place until released.

During the operation of the machine, the respective frames are placed inthe guide 19 near one end and the frames move along by the chain 16.Dining the movement of the respcc vc frames 8, the teasels thereol'ipass the cleaning belts 2; and. 2a and then pass the cleaning rollersand 26, said rollers being provided with bristles ofsome desired type.The belts and 2- are formed as aprons of special card cloth and act toloosen woolen (lakes or ravelings which have been tightly pressed orembedded in the teasels and held therein by the hooks of the teasels.

Card cloth a well known article used in cloth manulhcturingestablishments and consists of a special body or support with small.hook members projectingtherefrom and positioned in a compact body. Theaction of the hook members of the card cloth as the belts or aprons and24: move past the teasels is to loosen the ravelings caught therein andin fact, to loosen all parts of the teasels. Very little of theravelings are removed by the card cloth but what lit t le is removed maybe in turn removed from the card cloth aprons or belts and 2t by brushes2? and 8 positioned to clean the aprons 23 and continually so that thecard cloth will be clean as it engages the respective teasels.Preferably, the part of each of the aprons 223 and arranged in cordactwith the teasels, moves in a direction opposite to the movement of theteasels and also the brushes 2? and 28 revolve in a direction oppositeto the direction of movement of that part of the aprons which pass thesebrushes. lily arranging the parts in this manner, a thorough cleaningaction is provided both for the teasels and for the cleaning aprons and24-.

It will be understood that the frame 18 with the teasels mounted thereinwill move along at the speed of the chain 16 and, conserpiently, willgradually pass between the respective card cloth aprons and 2t and intoposition between the roller brushes 25 and 2(3. The side members 20 and21 of the guide 19 are cut away opposite the brushes 25 and 26 so thatthese brushes may freely engage the sides of the teacels for using asecond cleaning action. These brushes are connected with shafts 2%) and30, which shafts carry sprocket wheels at one end for acconnnodating therespective chains All and 32 which pass over suitable sprocket wheelssecured to the respective shafts S2 5 and ill which shafts are driven ashereinafter fully described. By these means, the brushes 25 and 26 arecontinually rotated and in order that these brushes may act from the topto the bottom of the teasels, the brushes are given an up and downmotion in addition to the rotary motion. This up and down motionproduced by having the ends of the shafts 29 and 30 journaled insuitable bearing boxes and 2156 which are provided with downwardlyextending sections 37 and -38. As all of these members are identical,the description of one set will apply to all.

As shown particularly in Figure (3, the sections 37 and 38 freely slidein guides 39 and d0 carried by the frame and are pivotally connected atrtl and 4-2 to the rods 43 and l t having on their ends eccentric straps45 and -16. These eccentric straps accommodate eccentrics l7 and 48which are rigidly secured to the shafts 41-9 and 50. As the shafts ll)and 50 extend full length of the brushes 25 and 26 and act on theeccentrics at each end as illustrated in Figures 1 and 2, the brushes 25and. 26 will be moved upwardly and downwardly at each end simultaneouslyand as they are rotated by the chains 31 and and associated parts, athorough cleaning action from top to bottom of the teasels will takeplace.

From Figure 5 it will be noted that the shafts d9 and 50 are rotated bythe worm gears 51 and which are rigidly secured thereto, said. wormgears being in turn driven by the worms 58 and 5-1- rigidly secured tothe shaft 55. The shaft 55 carries a bevel gear 56 at one end whichmeshes with the bevel gear 57 rigidly secured to the shaft 33, whichshaft is driven by power from any suitable source through the pulley 58.As the teasels leave the brushes 25 and 26, they pass between finalcleaning brushes and 60 operating on vertical spindles. After leavingthese brushes, the teasels are subjected to a blowing action through thecup (51 which is supplied with compressed air by any suitable means. Theair pump or other air supply acts through the tube 62 and therebyprovides an ample space of air for the cup (31 to finish the cleaningaction on the teasels.

After the frame carrying the teasels has moved past the cup 61 it movesonto the top run of a belt conveyor (33 which continues to move theframe until it strikes the end (Set of lever 65, which lever isbifurcated at the upper part and is pivotally connected at 66 to the rod67. The lever is maintained in the position shown in Figure 2 normallyby a spring 68 but when end (ii is moved by the frame 18, the leverswings and moves the clutch member 69 into engagement with the clutchmember '70 as lever (55 is connected with the clutch member (it) andsaid clutch IOU . axle 71. ;The clutch'member '70 is continuallyrotating as it is connected to a suitable 1r sprocket wheel 72. operatedby the chain 73, which chain is'operated'by sprocket wheel 74.- Thesprocket wheel 74 is con-.

nected by the. bevel gear 75 (Figure 4)] which in turn is actuated bythe bevel gear 76, which latter gear is rigidly secured to.- shaft 77and said shaft in turn is rigidly connected with the drum 78 on whichthe 79'which is rigidly secured tothe shaft 80 carrying the sprocketwheel'81. A chain 82 is carried by the sprocket wheel 81 and is operatedby sprocket wheel 83 secured to the shaft 84, which shaft is rigidlysecured to the sprocket wheel 13 operated by chainl6. y s

By the mechanism just described, the clutch member 70 is continuallyrotated and, consequently, whenever the clutch. member 69 is thrown intoaction, power will be immediately applied to the shaft or axle 71 forrotating the same. The direction of movement of. thesprocket wheel 72 issuch as to cause the shaft 71to move in such a direction that the rods67and 6'? will swing the pusher bar 85 as shown in dotted lines in Figure8 and, consequently, will push t1 frame 18 off of the belt 63 and'ontothe chute or guide 86 alongwhich it travels under the action of gravityuntil it is discharged.

From the mechanism described, itwill be seen that axwet set ofteaselsfull of ravel ings is placed in the machine and these teasels arecleaned and discharged.

In the accompanying drawings, the power is shown as being receivedthrough the pul-, ley wheel 58 from anysuitable source, said pulleywheel acting to drive the shaft 33, which shaft extends for the fulllength of the frame 11. Near the front of the frame a transverse shaft88 is provided which is connected to shaft 33 through the bevel gears 89and 90, shaft 88 having a sprocket wheel '91 secured thereto for drivingthe chain 92 which passes over a sprocket wheel 93 rigidly secured tothe shaft 94, which shaft also carries the, sprocket wheel 15. By thisconstruction the chain 16 is driven by power derived from the shaft 33.Near the shaft 88 a second transversely positioned shaft 95 is providedwhich receives power from shaft which receives power through the bevelgears 96 and 97, shaft 95 having a sprocket 'wheel 98 rigidly securedthereto for accomn'iodating the chain 99, which chain also passes over asprocket wheel 100 secured to the shaft 1.01, which shaft carriespulleys 102 and 103 as well as theeccentric disks 104 and 105.Thepulleys 102 and 103 accommo'date. the drive belts '106 and 107,

which belts pass over the respective pulleys mitted' to-these brushes.The eccentric disks 1 104 and'105. accommodate eccentric straps 109 and110, said straps operating the. ec-

centric rods 111'and 112 which in turn are. securedto the respectiveslides 113 and 114. Theshafts 115, 116,117 and 118 are connected tothese respective slides and accommodate the respective rollers 119, 120,121 and 122, which rollers accommodate therespective aprons of cardcloth 23v and 24. By this construction and arrangemenn the aprons-23'and 24 are reciprocatedor moved backand forth longitudinally of theteasel frame 18 while the aprons are caused to travel by, reason of: thefact" that the rollers Y 119 and 121 are continually driven during theoperation of the machine. As the card clo-thaprons become easily cloggedwith wool flakes or raveling, theyneed continual sprocket wheels 125 and126, said last men tioned sprocket wheels being-rigidly se-" cured to.the vertical shafts 127 and 128,

which shafts extend downwardly and through suitable bevel gears 129receive power from the respective shafts 33 and 34 through the bevelgears 130 and 131. "he back and forth movement of the slides 113 and 114is not very-great and, consequently,

the looseness of the chains 123 and 124 will compensate for this slightmovement without causing a disconnection of the respective parts. Theshaft 34 receives its power throughshaft 132, bevel gears 133, 134, 135and 136, gear.-136 being rigidly connected with shaft 33. The sprocketwheel 137 is connected to the shaft 132 and accommodatesthe chain 138,which chain passes over the sprocket wheel 139 rigidly secured to the. I

shaft 140 whereby said shaft is driven.

The shaft 140 acts to drive the pulley wheels 141 and 142 which carrysuitable belts 143 designed to engage the respective pulley wheels 144secured to the lower end of the shafts carrying brushes 59 and 60whereby these brushes are rotated. Power is taken olf the shafts 33 and34 respectively'forrotating the brushes 25 and 26. From Figures 1, 3 and5, it will benoted that the chain 31 passes over a pair ofguidingsprocket wheels 145 and 146 and from thence downwardly over asuitable sprocket wheel 147 secured to shaft A similar structure isprovided on the opposite side of the machine, namely, chain 32 extendsover the guiding;- sprockets 1i? and ill? and from thence over thesprocket Wheel 1 H secured to the shaft 2- The length of these chainsand the usual looseness provided, permits the brushes and 26 to beraised and lowered while being rotated by these chains. At the cud ofthe frame where belt (33 is located, the sprocket Wheel 1? is mounted ona suitable shaft 8i which has a second sprocket fl? secured theretowhich accommodates chain and, consequently drives this sprocliet anddrum 95.) whereby the belt 63 will. be properly driven at the requiredspeed. During the operation of the machine all oil? the parts arelunctioning at the same time and the various brushes and cleaning meansact upon the teascls as they pass gradually through the machine so thatthey are finally discha r red olli' belt 63 in a cleaned conditionthough still Wet. Though the teasels are wet or moist by reason ofhaving operated on moist cloth, there is an appreciable amount oli dustand dirt TillllGCl in the lint and tcasels. During the cleaningoperation, this dust becomes loose and would be more or lessobjectionable when the blast o'l air from cup (31 begins to function itmeans were not provided for accommodating the lust.

1 v indicated particularly in Figure (l, a hood (31 of sheet metal orother desired material is provided which encloses the various cleaning;elements except :t'or an opening at the bottom whereby when suction a1)-plicd to the outlet pipe 81", the dust removed from the teasels and lintwill be drawn oil to a diriscliargepoint. The lint also will be drawnoli and deposited at a suitable discharge point as otherwise it wouldmake undesirable deposits around the cleaning machine. When they leavethe belt (35 they drop upon the guide or skids 86 and by gravity slideto a disehi'u'ge point.

What I claim is LA teasel cleaning machine, comprising a guideivay forguiding a teasel carrying frame, means for forcing said frame along saidguideu'ay, a se'rics o't belt brushes arranged adjacent said guideivay,means for n'ioving the belt brushes to act on the teasels carried bysaid frame, said means causing the pcrating faces of the belt brushes totravel in a direction opposite to the travel or the teasels, and a setof rotating brushes acting on the teasels carried by said frame forcleaning the same as they move along said guide-Way.

Q. A teasel cleaning machine, comprising a guide substantially U-shapedin vertical cross section for receiving a teasel frame, means forcausing; said teasel frame \viththe teascls therein to move along saidguide, a plurality of belt brushes acting on said teasels means fordrivingsaid belt brushes so that the part thereol in contact with theteasels will move in the opposite direction to the movement of theteasel frame, and means for bodily reciprocating said belt brushes in adirection parallel to said guide while they are operatin f MAX POETZSGH.
